Social Security tax in 2026: the 6.2% rate, the $184,500 wage base and the maximum you can pay

What is the Social Security tax rate in 2026?

The Social Security tax rate is 6.2% of wages for the employee and 6.2% for the employer, 12.4% in total, according to IRS Topic 751. The rate is the same at every income level until you reach the annual wage base.

Social Security tax is one half of FICA; the other half is Medicare tax. On a pay stub it may be labeled Social Security, SS, OASDI or FICA-SS. For the full picture of both parts, see our FICA tax overview.

What is the Social Security wage base for 2026?

The Social Security wage base for 2026 is $184,500 (IRS Topic 751). The wage base is the most earnings per year that can be taxed for Social Security, and it is also the ceiling on earnings the Social Security Administration credits toward future benefits, which is why SSA calls it the contribution and benefit base.

The base rises most years because it is tied to growth in the national average wage. From 2025 to 2026 it went up $8,400, and for 2027 SSA has set it at $192,300, another $7,800. The 2027 Social Security wage base page shows how that figure was calculated.

What is the maximum Social Security tax you can pay?

The maximum Social Security tax an employee can owe for 2026 is $11,439, which is 6.2% of $184,500. Someone earning $184,500 and someone earning $900,000 pay exactly the same Social Security tax.

This Social Security tax limit applies only to the Social Security part. Medicare tax of 1.45% keeps going with no ceiling, and wages above $200,000 add a 0.9% surtax described on our Medicare tax rate page.

When in the year do high earners hit the cap?

You hit the cap on the paycheck that brings your year-to-date Social Security wages from one employer past $184,500. After that, the 6.2% deduction drops off and take-home pay rises until January.

Take an employee paid $240,000 a year in 24 semimonthly checks of $10,000. The first 18 checks each have $620 of Social Security tax withheld, for $180,000 of wages. The 19th check is taxed on only the remaining $4,500, or $279. Checks 20 through 24 have no Social Security tax, so each is $620 larger. Bonuses paid earlier in the year move that date forward.

What if I have two jobs and pay too much Social Security tax?

If two or more employers together withheld more than $11,439 of Social Security tax for 2026, you get the excess back as a credit on your federal return. Each employer must withhold on its own wages up to $184,500 because it cannot see your other job, so overpayment is common for people with two well-paid jobs.

Example: Job A pays $130,000 and withholds $8,060. Job B pays $90,000 and withholds $5,580. Total withheld is $13,640, or $2,201 more than the $11,439 maximum. You claim that $2,201 on the excess Social Security line of Schedule 3 (Form 1040), and it reduces your tax or increases your refund.

Rules for claiming the excess

• The credit is only for excess caused by more than one employer during the year (IRS Topic 608).
• If a single employer withheld too much, the employer should refund it; if it does not, file Form 843 with copies of your W-2 forms.
• On a joint return, each spouse figures excess Social Security tax separately; one spouse's overpayment cannot be combined with the other's wages.
• Check box 4 of every Form W-2 before filing. That box is the Social Security tax each employer withheld.

Your employers do not get their 6.2% share back in this situation. Only the employee's overpayment is refundable. If you want the extra income tax withholding from a second job to line up with your real bill, the W-4 withholding guide covers the Step 2 checkbox for multiple jobs.

How does the Social Security tax limit work for self-employed people?

Self-employed people pay 12.4% Social Security tax on net earnings (92.35% of net profit) up to the same $184,500 base. Wages from a job count first, so Schedule SE taxes only the room left under the cap.

For example, with $150,000 of W-2 Social Security wages, only $34,500 of 2026 self-employment earnings can be hit with the 12.4% rate. A person with no wages reaches the cap at about $199,783 of net profit, because 92.35% of that amount is $184,500. The self-employment tax rate page walks through the full Schedule SE calculation.

Does paying more Social Security tax raise your benefit?

Up to the wage base, yes: SSA uses your taxed earnings to figure your benefit, so higher covered earnings generally mean a higher retirement benefit. Earnings above the wage base are neither taxed nor credited, so pay above $184,500 in 2026 does not add to your benefit record.

Refunded excess from two jobs does not reduce your record either. The earnings are still credited up to the base; only the double-withheld tax comes back.
